Perhaps you should try some spelling variations:
"modified caging optimization algorithms" » "modified caging optimisation algorithm", "modified caging estimation algorithms", "modified caging estimation algorithm", "modified staffing optimization algorithms"
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified caging optimization algorithms") OR ("modified notion optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified caging optimization algorithms ) or ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimization algorithms") or ("modified notion optimization algorithms"))*.
